WITHDRAWN: Successful use of haemato-polyvalent anti-venom cross-neutralisation in the clinical management of Rhabdophis subminiatus (Rhabdophis keelback) envenomation

BackgroundAs the landscape becomes more urbanized, snakebites have increasingly become uncommon presentations to the emergency departments in Singapore, while snakebites causing significant envenomation are even rarer. Case reportIn this case report, we discuss a 55-year-old man who had significant envenomation from a Rhabdophis keelback (Rhabdophis subminiatus) and who was successfully treated with haemato-toxic polyvalent antivenom (HPAV). He initially presented with pain, swelling and bleeding over his wound. Due to a deterioration in his coagulation profile, he was given two doses of HPAV which is typically reserved for viperid snakes instead. Following administration of the anti-venom, the patient’s coagulation profile improved and the local soft tissue effects of the venom resolved. He did not manifest any adverse effects and was discharged uneventfully about 72 hours after the snakebite.The cross-neutralization potential of HPAV for Rhabdophis Colubrid venom in this case study suggests that there may be a possible common underlying chemical structure and pathophysiology among the venom proteins of various snake species. Given that Rhabdophis-specific antivenom is unavailable in most countries, this cross-neutralization strategy deserves further consideration and evaluation in similar circumstances. Why should an emergency physician be aware of this?The patient was successfully treated using HPAV with resolution of envenomation and discharged uneventfully. The possible cross neutralization potential of HPAV for Rhabdophis (colubrid) venom in our case may suggest a possible common underlying structure and pathophysiology of venom proteins amongst different snake species.

Exploring protective psychological factors of healthcare professionals during COVID-19 in Singapore: A qualitative study

This qualitative study aimed to explore the psychological impact of the Coronavirus 2019 (COVID-19) pandemic on frontline healthcare professionals (HCPs) both in primary care and hospital emergency departments in Singapore, to understand (1) the experience of HCPs during the outbreak, the new challenges faced on the job, how they were affected psycho-socially, (2) the support received, and (3) the protective factors of psychological distress. Purposive sampling was used to identify frontline HCPs, and those in managerial positions leading clinical teams. Semi-structured in-depth interviews were conducted with 39 participants from June to November 2020 via a video-conferencing platform, audio-recorded and transcribed verbatim. Thematic analysis using an inductive approach was conducted to elicit themes. We identified themes related to (i) the psychological impact they experienced, and (ii) the protective factors during this challenging period. In terms of psychological impact, work-related stressors such as physical burnout, loss of control and fear of infecting family were common themes. HCPs also experienced increased stress at home due to distancing measures they adhered to in order to protect their family. Themes related to psychological protective factors were also identified, such as resilience, team spirit, social support from peers, family and the public, and psychological readiness for the pandemic.

Transitional care strategies at emergency department for elderly patients: A multicentre study in Singapore

Introduction: Transitional care strategies (TCS) initiated for elderly patients prior to emergency department (ED) discharge are important for ensuring effective transition to other care settings. Such strategies have been shown to reduce avoidable acute admissions. This first nationwide study is targeted at public acute hospital EDs in Singapore, and aims to characterise TCS for ED-discharged elderly patients and understand the experiences of healthcare staff in the delivery of TCS. Method: Seven key informants (KIs), one per ED, completed an online structured questionnaire and semi-structured video conference interview from 8 May to 31 August 2021. The KIs were ED specialists and an ED-trained senior staff nurse who were knowledgeable in geriatric emergency care and had contributed to at least one elder-related TCS. Field notes were compiled, transcribed, anonymised and analysed using thematic analysis. Results: All 7 EDs have TCS as “usual care” available during office hours, at no extra cost to patients. Common components of TCS include screening, evaluation with comprehensive geriatric assessment, health education and follow-up telecare. TCS implementation was facilitated by organisational support in terms of established protocols and communication platforms, training and collaboration of a multidisciplinary team, and caregiver involvement. Obstacles faced include fragmented communication between personnel, limited resources, and poor buy-in from stakeholders. Conclusion: Understanding the heterogeneous characteristics of ED-TCS at various hospitals will aid the development of service typology and identify service opportunities. Provider experiences grouped into themes help to inform future strategies for TCS implementation. More research is needed to evaluate patient outcomes and cost-effectiveness of TCS.

Antibiotic expectation, behaviour, and receipt among patients presenting to emergency departments with uncomplicated upper respiratory tract infection during the COVID-19 pandemic

Pre-COVID-19 pandemic, patients who attended the emergency department (ED) for upper respiratory tract infection (URTI) were more likely to receive antibiotics if they expected them. These expectations could have changed with the change in health-seeking behaviour during the pandemic. We assessed the factors associated with antibiotics expectation and receipt for uncomplicated URTI patients in four Singapore EDs during the COVID-19 pandemic. We conducted a cross-sectional study on adult patients with URTI from March 2021 to March 2022 in four Singapore EDs and assessed the determinants of antibiotics expectation and receipt using multivariable logistic regression models. We also assessed the reasons patients expect antibiotics during their ED visit. Among 681 patients, 31.0% expected antibiotics while 8.7% received antibiotics during their ED visit. Factors (adjusted odds ratio [95% confidence interval]) that significantly influenced expectation for antibiotics include: 1) prior consultation for current illness with (6.56 [3.30-13.11]) or without (1.50 [1.01-2.23]) antibiotics prescribed; 2) anticipation for COVID-19 test (1.56 [1.01-2.41]); and 3) poor (2.16 [1.26-3.68]) to moderate (2.26 [1.33-3.84]) knowledge on antibiotics use and resistance. Patients expecting antibiotics were 10.6 times (10.64 [5.34-21.17]) more likely to receive antibiotics. Those with tertiary education were twice (2.20 [1.09-4.43]) as likely to receive antibiotics. In conclusion, patients with URTI who expected antibiotics to be prescribed remained more likely to receive it during the COVID-19 pandemic. This highlights the need for more public education on the non-necessity for antibiotics for URTI and COVID-19 to address the problem of antibiotic resistance.

Perceptions and coping strategies of junior doctors in a Paediatric Emergency Department in Singapore

Introduction: Perceptions towards the working and learning environment as well as coping mechanisms have been studied across different healthcare sectors. They have shown to reduce stress and burnout. However, perceptions of the work environment in the Emergency Department (ED) setting have not been studied in depth. The literature surrounding coping mechanisms also mostly focuses on their impacts rather than the mechanisms utilised. In addition, these were often investigated using surveys. This study aimed to use a phenomenological approach to explore the perceptions and coping strategies of junior doctors working in a paediatric ED. Methods: Sixteen junior doctors working in the Paediatric ED were recruited. Semi-structured interviews were conducted after conducting literature reviews. Data was collected until saturation point. All interviews were recorded and transcribed verbatim manually and subsequently analysed. Results: The greatest fears of junior doctors starting their paediatric emergency posting were lack of knowledge due to inexperience in the subspecialty; fear of the work environment due to unfamiliarity as well as workload and the intrinsic high-stress environment. The main coping strategies were ensuring clinical safety, obtaining psychosocial support from loved ones and colleagues, and placing focus on spirituality and wellbeing. Conclusion: In this study, the perceptions and coping strategies of the junior doctors in the Paediatric ED were explored. The findings from this study will help to structure and improve the support given to future junior doctors who rotate to the department as well as better orientate them to allay their pre-conceived notions.

Applying Andersen's healthcare utilization model to assess factors influencing patients' expectations for diagnostic tests at emergency department visits during the COVID-19 pandemic.

The uncertainties surrounding the COVID-19 pandemic led to a surge in non-urgent emergency department (ED) attendance among people presenting with upper respiratory tract infection (URTI) symptoms. These non-urgent visits, often manageable in primary care, exacerbated ED overcrowding, which could compromise the quality of ED services. Understanding patients' expectations and the reasons for these ED visits is imperative to mitigate the problem of ED overcrowding. Hence, we assessed the factors influencing patients' expectations for diagnostic tests during their ED visits for uncomplicated URTI during different phases of the pandemic. We conducted a cross-sectional study on adults with URTI symptoms seeking care at four public EDs in Singapore between March 2021 and March 2022. We segmented the study period into three COVID-19 pandemic phases-containment, transition, and mitigation. The outcome variables are whether patients expected (1) a COVID-19-specific diagnostic test, (2) a non-COVID-19-specific diagnostic test, (3) both COVID-19-specific and non-COVID-19-specific diagnostic tests, or (4) no diagnostic test. We built a multinomial regression model with backward stepwise selection and classified the findings according to Andersen's healthcare utilization model. The mean age of participants was 34.5 (12.7) years. Factors (adjusted odds ratio [95% confidence interval]) influencing expectations for a COVID-19-specific diagnostic test in the ED include younger age {21-40 years: (2.98 [1.04-8.55])}, no prior clinical consultation (2.10 [1.13-3.89]), adherence to employer's health policy (3.70 [1.79-7.67]), perceived non-severity of illness (2.50 [1.39-4.55]), being worried about contracting COVID-19 (2.29 [1.11-4.69]), and during the transition phase of the pandemic (2.29 [1.15-4.56]). Being non-employed influenced the expectation for non-COVID-19-specific diagnostic tests (3.83 [1.26-11.66]). Factors influencing expectations for both COVID-19-specific and non-COVID-19-specific tests include younger age {21-40 years: (3.61 [1.26-10.38]); 41-60 years: (4.49 [1.43-14.13])}, adherence to employer's health policy (2.94 [1.41-6.14]), being worried about contracting COVID-19 (2.95 [1.45- 5.99]), and during the transition (2.03 [1.02-4.06]) and mitigation (2.02 [1.03-3.97]) phases of the pandemic. Patients' expectations for diagnostic tests during ED visits for uncomplicated URTI were dynamic across the COVID-19 pandemic phases. Expectations for COVID-19-specific diagnostic tests for ED visits for uncomplicated URTI were higher among younger individuals and those worried about contracting COVID-19 during the COVID-19 pandemic. Future studies are required to enhance public communications on the availability of diagnostic services in primary care and public education on self-management of emerging infectious diseases such as COVID-19.

Why Are Some Male Alcohol Misuse Disorder Patients High Utilisers of Emergency Health Services? An Asian Qualitative Study.

Background: Certain alcohol misuse patients heavily utilise the Emergency Department (ED) and Emergency Medical Services (EMS) and may present with intoxication or long-term sequelae of alcohol misuse. Our study explored reasons for repeated ED/EMS utilisation and sought to understand perpetuating and protective factors for drinking. Methods: Face-to-face semi-structured qualitative interviews were conducted. Participants were recruited from an ED in Singapore. Interviews were audio-recorded, transcribed verbatim and underwent manual thematic analysis. Emergent themes were independently reviewed for agreement. Data from medical records, interview transcripts, and field notes were triangulated for analysis. Results: All participants were male (n = 20) with an average age of 55.6 years (SD = 8.86). Most were unemployed (75%), did not have tertiary education (75%), were divorced (55%), and had pre-existing psychiatric conditions (60%) and chronic cardiovascular conditions (75%). Reasons for utilisation included a perceived need due to symptoms, although sometimes it was bystanders who called the ambulance. ED/EMS was preferred due to the perceived higher quality and speed of care. Persistent drinking was attributed to social and environmental factors, and as a coping mechanism for stressors. Rehabilitation programs and meaningful activities reduced drinking tendencies. Conclusion: ED/EMS provide sought-after services for alcohol misuse patients, resulting in high utilisation. Social and medical intervention could improve drinking behaviours and decrease overall ED/EMS utilisation.

Frequent attenders to multiple emergency departments in Singapore

The problem of overcrowding, of which access block is one of the main causes, continues to plague emergency departments (EDs) worldwide.1 Some of its negative effects include adverse impact on patient safety, medical errors and staff burnout. In addition, high volume of patients waiting to be seen (ED input) exacerbates overcrowding. Frequent attenders (FAs), defined

COVID-19 vaccination-related attendance at a pediatric emergency department in Singapore among 12- to 18-year old adolescents.

BackgroundSingapore was one of the first countries to begin COVID-19 vaccination with the BNT162b2 vaccine for adolescents aged 12–18 years. This study evaluates the incidence of COVID-19 vaccine related attendances to a Pediatric Emergency Department (PED) to understand post-vaccination health behaviors among adolescents.MethodsThis was a retrospective review of electronic medical records over a 4 month period, from the start of the adolescent vaccination drive to when more than 85% of this group had been fully vaccinated.ResultsThe incidence of COVID-19 vaccination-related presentations to our PED was 3.1% over 4 months (291 of 9387 PED attendances), with a peak daily incidence of 15.4% (14 of 91 attendances). Presentations were characterized by severity into: severe (3.4%), moderate (7.9%) or mild (88.7%) based on predefined criteria. The most common presenting complaints were chest pain (58.8%), dyspnea (28.2%) and palpitations (22.6%). Hospitalization was required in only 6.2% of attendances. Patients with moderate-severe presentations were 0.7 years older (p = 0.030), more likely to have underlying drug allergies (p = 0.048) and had higher rates of hospitalization (p < 0.005) compared to mild presentations. Despite concerns of cardiac inflammation, chest pain related attendances were less likely to be severe (p < 0.005) with reduced hospitalization need (p = 0.043) compared to other presentations. Investigations beyond clinical assessment comprised 91% of attendances, but abnormalities were only found in 6.4% cases.ConclusionOur study supports current evidence that COVID-19 vaccination is safe amongst adolescents. We highlight the health behaviors among adolescents post-vaccination, which is partly driven by media reports on vaccine side effects and an element of anxiety. While most of the presentations were mild, these can have implications on health resource utilization, particularly in an ongoing pandemic. As healthcare workers, we have an ongoing role to ensure accurate information on vaccine safety is communicated effectively to the public.

Determinants of emergency department utilisation by older adults in Singapore: A systematic review

Adults aged ≥60 years contribute to disproportionately higher visits to the emergency departments (ED). We performed a systematic review to examine the reasons why older persons visit the ED in Singapore. We searched Medline, Embase and Scopus from January 2000 to December 2021 for studies reporting on ED utilisation by older adults in Singapore, and included studies that investigated determinants of ED utilisation. Statistically significant determinants and their effect sizes were extracted. Determinants of ED utilisation were organised using Andersen and Newman's model. Quality of studies was evaluated using Newcastle Ottawa Scale and Critical Appraisal Skills Programme. The search yielded 138 articles, of which 7 were used for analysis. Among the significant individual determinants were predisposing (staying in public rental housing, religiosity, loneliness, poorer coping), enabling (caregiver distress from behavioural and psychological symptoms of dementia) and health factors (multimorbidity in patients with dementia, frailty, primary care visit in last 6 months, better treatment adherence). The 7 included studies are of moderate quality and none of them employed conceptual frameworks to organise determinants of ED utilisation. The major determinants of ED utilisation by older adults in Singapore were largely individual factors. Evaluation of societal determinants of ED utilisation was lacking in the included studies. There is a need for a more holistic examination of determinants of ED utilisation locally based on conceptual models of health seeking behaviours.

Neonatal presentations to the paediatric emergency department in Singapore.

This study aimed to characterise neonatal paediatric emergency department (PED) visits, analyse the main paediatric illnesses and establish associations of these demographics with the readmission rates and severity of their presentation. A retrospective analysis of neonates (aged <28 days) presenting to the PEDs of our hospital over seven months was performed. Associations between the clinical and demographic data of admissions to the PED and inpatient admissions were analysed. In total, 1,200 neonates presented during the study period, 79.4% of whom presented at less than 15 days since birth. Length of stay in the PED was less than four hours for 94.0% of the neonates. Predominant triage categories comprised non-P1 cases (97.5%). The main diagnoses at the PED were neonatal jaundice (NNJ; 66.8%) and neonatal pyrexia (NNP; 14.6%), which corresponded to the main diagnoses upon discharge from the hospital: NNJ (68.4%) and NNP (19.6%). 48.2% of neonates were referred from polyclinics or other clinics. 57.7% of the neonates were admitted. Interestingly, 87.0% of the well babies who presented to the emergency department were brought in owing to parental concerns by the parents themselves, without prior consultation with the doctor. Outpatient management of NNJ can be considered. Caregivers should be provided better education regarding normal physiological characteristics of newborns through standardised educational materials. Other potential avenues for parents to seek medical advice, for example hotlines and ChatBots such as the recently piloted 'Urgent Paediatric Advice Line' online service, should be considered.

Determinants of antibiotic over-prescribing for upper respiratory tract infections in an emergency department with good primary care access: a quantitative analysis

Upper respiratory tract infections (URTI) account for the highest proportion of non-urgent visits to the emergency department (ED), resulting in unnecessary antibiotic use. This study sought to understand the determinants of antibiotic prescribing for URTI among 130 junior physicians in a busy adult ED in Singapore. Forty-four Likert-scale statements were developed with reference to a prior qualitative study, followed by an anonymous cross-sectional survey among ED junior physicians. Data analysis was performed with factor reduction and multivariable logistic regression. One-in-six (16.9%) physicians were high antibiotic prescribers (self-reported antibiotic prescribing rate of >30% of URTI patients). After adjusting for place of medical education and years of practice as a physician, perceived over-prescribing of antibiotics in the ED (adjusted odds ratio (OR) 2.37, 95% confidence interval (CI) (1.15, 4.86), P=0.019) and perceived compliance with the antibiotic prescribing practices in the ED (adjusted OR 2.10, 95% CI (1.02, 4.30), P=0.043) were positively associated with high antibiotic prescribing. In contrast, high antibiotic prescribers were 6.67 times (95% CI (1.67, 25.0), P=0.007) less likely to treat and manage patients with URTI symptomatically and 7.12 times (95% CI (1.28, 39.66), P=0.025) more likely to depend on diagnostic tests to prescribe antibiotics than the regular antibiotic prescribers. Organizational-related factors (organizational norms and culture) were strong determinants of antibiotic prescribing practices for uncomplicated URTI in the ED. Other contributing factors include diagnostic uncertainty and knowledge gaps. Role-modelling of institutional best practice norms and clinical decision support tools based on local epidemiology can optimize antibiotic prescribing in the ED.

The “timeless” use of influenza-like illness criteria for influenza detection in the tropics

ObjectiveWe assessed the performance of influenza-like illness (ILI) case definitions by the Centers for Disease Control and Prevention (CDC), European Centers for Disease Control and Prevention and World Health Organization (WHO) in the tropics where seasonal patterns of respiratory viruses in acute upper respiratory tract infections (AURTIs) are ill-defined. MethodsClinical data and samples for respiratory multiplex polymerase chain reaction test were collected from 717 consecutive patients attending an emergency department in Singapore for uncomplicated AURTI in 2016–2018. ResultsInfluenza (20.6%), rhinoviruses (14.4%), and coronaviruses (3.6%) were the most common viral pathogens identified. Biannual peaks with year-round activity were identified for influenza. Although higher rhinovirus activity was observed in inter-influenza seasonal periods, rhinoviruses and coronaviruses circulated year-round without distinct seasonal patterns. During high influenza activity months, the CDC and WHO ILI case definitions had moderate-to-high positive likelihood ratio (LR+) of 3.8–6.8 and 4.5–10.7, respectively, for ruling in influenza. They had moderately-high LR + of 3.3–3.8 and 3.9–4.6 for diagnosing influenza during other months. The ILI case definitions had high specificity (77.2%–85.4%) for rhinoviruses and coronaviruses. ConclusionThe CDC and WHO ILI case definitions can be applied to clinically diagnose influenza in the tropics, regardless of the time of the year.

Paediatric emergency department attendances during COVID-19 and SARS in Singapore

We evaluated the impact of public health measures on paediatric emergency department attendances during the COVID-19 and severe acute respiratory syndrome (SARS) outbreaks in Singapore. Between 1 January 2020 and 31 July 2020, we retrospectively reviewed paediatric emergency department attendances and admissions in a tertiary paediatric hospital in Singapore before and after a national lockdown to combat the spread of COVID-19 in Singapore. Hospital attendances and admissions were compared with data from a corresponding period in 2019 (1 January 2019 to 31 July 2019), as well as during and after the SARS outbreak (1 January 2003 to 31 December 2004). Compared with a corresponding non-outbreak period, emergency department attendances decreased in line with nationwide public health measures during the COVID-19 and SARS outbreaks (2020 and 2003 respectively), before increasing gradually following lifting of restrictions, albeit not to recorded levels before these outbreaks. During the COVID-19 outbreak, mean daily attendances decreased by 40%, from 458 per day in January-July 2019, to 274 per day in January-July 2020. The absolute number of hospital inpatient admissions decreased by 37% from January-July 2019 (19,629) to January-July 2020 (12,304). The proportion of emergency department attendances requiring admission remained similar: 20% in January-July 2019 and 21% in January-July 2020. Nationwide public health measures in Singapore have had an impact on paediatric emergency department attendances and hospital inpatient admissions. Data from this study could inform planning and resource allocation for emergency departments in Singapore and internationally.

A retrospective review of trampoline-related injuries presenting to a paediatric emergency department in Singapore

Trampolining is a popular activity. However, to our knowledge, no studies on paediatric trampoline-related injuries (TRIs) have been conducted in Asia. We aimed to provide an Asian perspective on paediatric TRIs and evaluate current safety measures. Patients aged under 16 years who presented to the emergency department at KK Women's and Children's Hospital, Singapore, from March 2012 to June 2016 with a TRI were identified from the National Trauma Registry. Data was collated retrospectively focusing on age, location of the trampoline, mechanism and location of injury, treatment, disposition, and follow-up treatment. 137 children were seen for a TRI during this period. There was even representation across age groups (< 6 years, 6-11 years and 11-16 years). 60.6% of these injuries occurred in a public trampoline park, and a smaller proportion involved home and school trampolines. 61.3% of injuries occurred on the trampoline and 25.5% involved a fall off it, while the remaining were incurred by hitting the trampoline frame. The most common injury was soft tissue injury, followed by fractures and dislocations, of which 16.7% required surgical intervention. Most patients were discharged to an outpatient clinic. 14.6% of all patients required admission and 9.5% eventually required surgical intervention. There were three stable head injuries and no cervical spine injuries or deaths. The existence of trampoline parks has contributed to a rise in TRIs. We recommend measures such as general education, changes in the setup around the trampoline, increasing the age limit for trampolining, adult supervision and discouraging double bouncing.

Modeling Emergency Department crowding: Restoring the balance between demand for and supply of emergency medicine.

Emergency Departments (EDs) worldwide are confronted with rising patient volumes causing significant strains on both Emergency Medicine and entire healthcare systems. Consequently, many EDs are in a situation where the number of patients in the ED is temporarily beyond the capacity for which the ED is designed and resourced to manage-a phenomenon called Emergency Department (ED) crowding. ED crowding can impair the quality of care delivered to patients and lead to longer patient waiting times for ED doctor's consult (time to provider) and admission to the hospital ward. In Singapore, total ED attendance at public hospitals has grown significantly, that is, roughly 5.57% per year between 2005 and 2016 and, therefore, emergency physicians have to cope with patient volumes above the safe workload. The purpose of this study is to create a virtual ED that closely maps the processes of a hospital-based ED in Singapore using system dynamics, that is, a computer simulation method, in order to visualize, simulate, and improve patient flows within the ED. Based on the simulation model (virtual ED), we analyze four policies: (i) co-location of primary care services within the ED, (ii) increase in the capacity of doctors, (iii) a more efficient patient transfer to inpatient hospital wards, and (iv) a combination of policies (i) to (iii). Among the tested policies, the co-location of primary care services has the largest impact on patients' average length of stay (ALOS) in the ED. This implies that decanting non-emergency lower acuity patients from the ED to an adjacent primary care clinic significantly relieves the burden on ED operations. Generally, in Singapore, there is a tendency to strengthen primary care and to educate patients to see their general practitioners first in case of non-life threatening, acute illness.

Reorganising the emergency department to manage the COVID-19 outbreak

BackgroundThe COVID-19 disease outbreak that first surfaced in Wuhan, China, in December 2019, has taken the world by storm and ravaged almost every country in the world. Emergency departments (ED) in hospitals are on the frontlines, serving an essential function in identifying these patients, isolating them early whilst providing urgent medical care. This outbreak has reinforced the role of Emergency Medicine in public health. This paper documents the challenges faced and measures taken by a tertiary hospital’s ED in Singapore, in response to the outbreak.Main bodyThe ED detected the first case of COVID-19 in Singapore on 22 January 2020 in a Chinese tourist and also the first case of locally transmitted COVID-19 on 3 February 2020. The patient journeys through the patient reception area in the ED and undergoes fever screening before being shunted to isolation areas within the ED. Management and disposition of suspect COVID-19 patients are guided by a close-knit collaboration between ED and department of infectious diseases. With increasing number of patients, back-up plans for expansion of space and staff augmentation have been enacted. Staff safety is also of utmost importance, with provision and guidelines for personal protective equipment and team segregation to ensure no cross-contamination across staff. These have been made possible with an early setup of an operational command and control structure within the ED, managing manpower, logistics, operations, communication and information management and liaison with other clinical departments.ConclusionWith the large numbers of undifferentiated patients managed by the ED to date, more than 820 patients with COVID-19 have been identified in the hospital. Not a single member of the staff of the SGH Emergency Department has come down with the illness. The various measures undertaken by the department have helped to ensure good staff morale and strict adherence to safety procedures. We share the lessons learnt so that others who manage EDs around the world can benefit from our experience.

Complementary and Alternative Medicine Use Among Pediatric Emergency Department Patients in Singapore.

The aim of the study was to determine the prevalence and types of complementary and alternative medicine (CAM) use among pediatric emergency department (ED) patients and perceptions of CAM among the caregivers who administer CAM in Singapore. A survey was administered in a Singapore ED (June 2016-June 2017). A convenience sample of parents/carers accompanying pediatric patients completed a self-administered questionnaire. The primary outcome measures were prevalence of CAM use and perceptions of CAM. Parents/carers of 610 patients participated. Four hundred seventy-five (78.0%, 95% confidence interval, 74.5-81.0) had taken a CAM within the previous 12 months and 110 (18.1%; 95% confidence interval, 14.8-21.0) had taken a CAM on the day of presentation. There were no sex differences between CAM users and nonusers (P = 0.691). The use of CAM was more common among preschool children and younger (62.9%). There was no difference in CAM use among those with and without chronic disease (P = 0.878). Vitamins/supplements, cod liver oil, and probiotics were the most commonly used CAM. A total of 0.7% of CAM use was reported to the ED doctor. There were no adverse effects reported. The perception that CAMs are safe was more common among parents or caregivers who had administered CAM (P = 0.008). Complementary and alternative medicine use is very common among pediatric ED patients in Singapore and is more prevalent than in Australia and the United Kingdom. However, it is not always reported to the doctor. Parents or caregivers who administer CAM are more likely to perceive CAMs to be safe.

Does video laryngoscopy or direct laryngoscopy affect first-pass success rates for intubation among attending and non-attending emergency physicians in the emergency department?

Background: To our knowledge, there has been no study comparing intubation characteristics between attending and non-attending emergency physicians in Southeast Asia. We aim to identify whether the use of direct laryngoscopy compared to video laryngoscopy affects first-pass success rates between attending emergency physicians and non-attending emergency physicians. Materials and methods: Retrospective analysis of data from 2009 to 2016 in an existing airway registry managed by an academic Emergency Department in Singapore. Primary outcome was first-pass success intubation rate. Secondary outcome was first-pass success rate for difficult intubations. Difficult intubations were defined as LEMON (Look externally, Evaluate 3-3-2 rule, Mallampati score, Obstruction, Neck mobility) score of more than 1. Results: There were a total of 2909 intubations. Attending emergency physicians conducted 1748 intubations, while non-attending emergency physicians conducted 1161 intubations. The first-pass success rates for AEP were 84.2% and 67.4% for non-attending emergency physicians. Direct laryngoscopy was used in 86.2% of intubation by attending emergency physicians compared to 89.0% in the intubation by non-attending emergency physicians. Also, 7.6% of intubations by the attending emergency physicians were difficult compared to 8.8% by the non-attending emergency physicians (p = 0.25). Logistic regression of the effect of laryngoscopy device on first-pass success in all intubations showed a negative association with video laryngoscopy (odds ratio, 0.70; 95% confidence interval, 0.56–0.88). In the subgroup of difficult intubations, non-attending emergency physicians are 1.54 times (95% confidence interval, 0.53–4.42) as likely to have first-pass success with video laryngoscopy compared to that with direct laryngoscopy. On the contrary, in the subgroup of difficult intubations, attending emergency physicians are 0.90 times (95% confidence interval, 0.38–2.12) as likely to have first-pass success with video laryngoscopy compared to that with direct laryngoscopy. Conclusion: Our study showed that video laryngoscopy has a lower first-pass success rate for all intubations in general. Intubations performed by attending emergency physicians with direct laryngoscopy were associated with a higher first-pass success rate.
